I’m still reading.

I almost bought a Mugo Pine from the sale table at a garden center this Fall, but I figure they will be available again later this year and I’m just not sure what I want, yet. I do have the Eastern Red Cedar from my yard in the pot on my deck. Since it’s only a year old, I expect it will be a while before I actually do anything besides let it get some girth.

My friend Patti has taken up pottery in her retirement and she offered to make me a pot, or possibly potS, for my little trees.  I wasn’t finding an easy answer to “how big?” and asked on /Bonsai.  I was directed to http://www.bonsai4me.com/AdvTech/ATChoosing%20the%20Right%20Pot%20for%20your%20Bonsai.htm and found:

The general rule of thumb is that the pots depth should be equal to the diameter of the trunk just above soil level.
For oval or rectangular pots, the length of the pot should be 2/3 the height of the tree.
For round pots, the diameter of the pot should be 1/3 the height of the tree.
For trees with especially wide canopies a wider pot can be necessary and this can be compensated by using a slightly shallower pot.
As equally, a tree with a very thick trunk (in comparison with the height of the tree) may suit a slightly deeper but narrower pot.

It’s a start.
